Which ds0-group option should you select to send automated number identification information on outbound calls for this digital T1 voice circuit?
Click on the arrows to vote for the correct answerA. A. C. D. E.
E&amp;M signaling is often the preferred option for CAS because it avoids glare, it provides answer/disconnect supervision and it can receive Automatic Number Identification (ANI) with FGD and send ANI with FGD-EANA.
In other words, you can have 1 channel-group for incoming calls and 1 channel-group for outgoing calls.
